Staff Software Engineer

Be part of something.

Global logistics is one of the most complex systems on earth — and we are on a mission to simplify that.

Yojee is building the digital nervous system for freight forwarding, customs brokerage and carrier operations across air, ocean and road. With MOSAIC (freight forwarders) and TCMS (carriers & shippers), we’re connecting every movement, event, document, and workflow into one integrated ecosystem.

The architectural decisions we make in the next 12–18 months will define the backbone of the company and the global landscape of international logistics for years.

This is where you come in.

The Role

Yojee is looking for a Staff Software Engineer who can shape the technical direction of our platform, guide engineering teams, and build scalable, maintainable systems that stand the test of time.

You will work across MOSAIC, TCMS, integrations, event processing, and front-end architecture patterns — ensuring coherence, reliability, and effectiveness across modules. This is a hands‑on role. You will design, code, and drive best practices.
